I've been looking for this movie for years. When I was a kid I saw a 1950s/60s sci fi about astronauts that land on Mars (I think it was Mars) but the Martians transform the landing site to look like the astronauts' childhood hometowns on earth and the Martians change their appearance to resemble the astronauts' friends and family. Gradually the astronauts realize Aunt Mabel really isn't aunt Mabel and the Martians divulge their dastardly intentions. Very creepy movie. This is all I can recall after 30 years.
This very definitely sounds like an adaptation of the Ray Bradbury story The Third Expedition (also published as Mars Is Heaven) from The Martian Chronicles. However I was unable to find a matching movie in IMDB.
It is The Martian Chronicles by Ray Bradbury featuring Rock Hudson. I saw this as a kid on TV in the 1970s and thought it was spooky. I managed to track down a DVD on eBay and say all there chapters. Some parts I fast forwarded as I got bored. Very retro look. The best part is indeed where they land on Mars and the Martians tap into the astronauts minds to make them believe they are back home with loved ones.
